Issue/Introduction
"Unknown Error in .JavaStart() : Foreign binary JVM could not be loaded" when loading terrJava, parallel or SDBC package.
Environment
All supported environments
Resolution
The TERR instance's "JAVA_HOME" environment variable has been set to point to a Java Runtime Environment (JRE) whose bitness (32-bit vs 64-bit) does not match the bitness of the TERR instance. Note that in Windows on a 64-bit machine, the string "Program Files (x86)" in a file path indicates that it is the installation path for a 32-bit application.
Solution:
When using 64-bit TERR, set the TERR instance's "JAVA_HOME" environment variable to point to a 64-bit Java Runtime Environment.
When using 32-bit TERR, set the TERR instance's "JAVA_HOME" environment variable to point to a 32-bit Java Runtime Environment.
Background:
To use any of the following packages in TERR,
parallel
sjdbc
terrJava
you must have a bit-matching (32-bit or 64-bit) version of the Java Runtime Environment (JRE) installed. After you have installed a bit-matching version of Java, make certain to set the JAVA_HOME environment variable on your machine to point to the installation path for the Java installation of the correct bitness. Once this is done, restart TERR and load the package again.
You can also set the JAVA_HOME environment variable within the TERR Console session before you load the package, using a call similar to the following:
Sys.setenv( JAVA_HOME = "C:/Program Files/Java/jdk1.7.0_45" )
Note that R and TERR use the slash ("/") as the file path separator, even on Windows. A single backslash ("\") will not work.
Once this has been done, try to load the package again.
Solution:
When using 64-bit TERR, set the TERR instance's "JAVA_HOME" environment variable to point to a 64-bit Java Runtime Environment.
When using 32-bit TERR, set the TERR instance's "JAVA_HOME" environment variable to point to a 32-bit Java Runtime Environment.
